Find the slop of the line identified by the equation 4x plus 5y equal 20?
4x+5y = 20 5y = -4x+20 y = -4/5x+4 So the slope is -4/5 or as -0.8 and the y intercept is 4
Indentify the slope of 4x plus 5y equals 20?
4x + 5y = 20 5y = -4x + 20 y = (-4/5)x + 20/5 Now that the equation has been rewritten in standard form, the slope is the cofficient of x, -4/5 [or -0.8]
What is the x-intercept in this linear equation y -4x 4?
Without an equality sign it cannot be considered as an equation and the + or - value for 4 has not been given
What is 4x plus 2x plus 2 equals 26?
It is an equation and the value of x is 4
How do you solve this linear equation 4x-7y equals -4 x plus y equals 0?
4x-7y = -4 4(x+y = 0) Mutiply all terms in the bottom equation by 4: 4x-7y = -4 4x+4y = 0 Subtract the bottom equation from the top equation: -11y = -4 Divide both sides by -11 remembering that a minus divided into a minus becomes a plus: y = 4/11 Substitute the value of y into the original equations to find the value of x: Therefore: x = -4/11 and y = 4/11
What is the value of x in the equation 4x - 20 equals -4?
4x - 20 = -44x = 16x = 4
Find the slop of the line identified by the equation 4x plus 5y equal 20?
4x+5y = 20 5y = -4x+20 y = -4/5x+4 So the slope is -4/5 or as -0.8 and the y intercept is 4
Find the value of x: 2(4x + 4) = (4x - 12)?
2(4x + 4) = (4x - 12) 8x + 8 = 4x - 12 8x - 4x + 8 = 4x - 4x - 12 4x + 8 = -12 4x + 8 - 8 = -12 - 8 4x = -20 4x/4 = -20/4 x = -5
What is the answer to 4x plus 8y equals 20 and -4x plus 2y equals -30 by solving using elimination?
4x + 8y = 20-4x + 2y = -30First add equations 1. & 2. to get:(4x + -4x) + (8y + 2y) = 20 + -30⇒ 10y = -10⇒ y = -1Multiply equation 2. by 4 and subtract it from equation 1:4x + 8y = 20-16x + 8y = -120⇒ (4x - -16x) + (8y - 8y) = 20 - -120⇒ 20x = 140⇒ x = 7Solution x = 7, y = -1Alternatively, to find x, now that y is known to be -1:Substitute y = -1 into equation 1. to give:4x + 8(-1) = 20⇒ 4x -8 = 20⇒ 4x = 28⇒ x = 7The solution can be checked y substituting the values found for x and y in to equation 2. and checking it is the correct value:-4x + 2y = -4(7) + 2(-1)= -28 + -2= -30as required, so the solution is correct.
What is the answer to 4x plus 4 equals 20?
7 3x + 4 = 19 3x = 15 x = 5
Indentify the slope of 4x plus 5y equals 20?
4x + 5y = 20 5y = -4x + 20 y = (-4/5)x + 20/5 Now that the equation has been rewritten in standard form, the slope is the cofficient of x, -4/5 [or -0.8]
What is the x-intercept in this linear equation y -4x 4?
Without an equality sign it cannot be considered as an equation and the + or - value for 4 has not been given
What 6x plus 3 equals 4x plus 11?
It is an equation and the value of x is 4
What is 4x plus 2x plus 2 equals 26?
It is an equation and the value of x is 4
How do you solve this linear equation 4x-7y equals -4 x plus y equals 0?
4x-7y = -4 4(x+y = 0) Mutiply all terms in the bottom equation by 4: 4x-7y = -4 4x+4y = 0 Subtract the bottom equation from the top equation: -11y = -4 Divide both sides by -11 remembering that a minus divided into a minus becomes a plus: y = 4/11 Substitute the value of y into the original equations to find the value of x: Therefore: x = -4/11 and y = 4/11
What is the value of x in the equation -4x plus 2 26?
If the equation is -4x + 2 = 26, then you can solve like so: -4x + 2 = 26 -4x = 26 - 2 = 24 4x = -24 x = -6 Check: -6 * -4 = 24, 24 + 2 = 26
How do you solve 2x-y equals 4 and 2y equals 4x-6 using the substitution method?
2x-y = 4 and 2y = 4x-6 pick either equation and solve for one of the variables the first equation: y = -4 + 2x plug in the value of variable you solved for into the other equation 2(-4 + 2x) = 4x -6 then solve -8 + 2x = 4x-6 -2 = 2x x= -1 then plug in the value you have found into either original equation to find the value of the other variable 2(-1) - y = 4 -2 - y = 4 -y = 6 y = -6
